C# 路易斯+；单个Microsoft Bot框架中的CustomVision

我是C#的新手，我想制作一个机器人，将Luis services和customvision混合在一起

我希望用户能够发送一个图像或文本到机器人

我从microsoft bot框架“核心bot”和图像处理bot**（*，**）开始

目前，我确实有这段代码，它是两个示例之间的混合代码

我是c#的新手，因此如果您对以上内容有任何见解，我将不胜感激

这实际上是重复@stuartd在评论中所说的内容。 方法

MessageFactory.attachment

返回一个

IMessageActivity

，因此最好使用第二个变量，而不是

活动回复

，以避免强制转换

case FlightBooking.Intent.Weather:
 // We haven't implemented the GetWeatherDialog so we just display a TODO message.
 var getWeatherMessageText = "TODO: get weather flow here";
 var getWeatherMessage = MessageFactory.Text(getWeatherMessageText, getWeatherMessageText, InputHints.IgnoringInput);
 await turnContext.SendActivityAsync(getWeatherMessage, cancellationToken);
 var attachments = new List<Attachment>();
 meesageReply = MessageFactory.Attachment(attachments); //new variable
 messageReply.Attachments.Add(Cards.CreateAdaptiveCardAttachment());
 break;

case FlightBooking.Intent.Weather：
//我们没有实现GetWeatherDialog，所以只显示一条TODO消息。
var getWeatherMessageText=“TODO:在此处获取天气流量”；
var getWeatherMessage=MessageFactory.Text（getWeatherMessageText，getWeatherMessageText，InputHints.IgnoringInput）；
等待turnContext.SendActivityAsync（getWeatherMessage，cancellationToken）；
var attachments=新列表（）；
meesageReply=MessageFactory.Attachment（附件）//新变量
messageReply.Attachments.Add（Cards.CreateAdaptiveCardAttachment（））；
打破

错误消息告诉您要执行以下操作：1）为第二个

回复使用不同的变量名，2）在
案例飞行预订的末尾添加
break
语句。Intent.Weather:
code
case FlightBooking.Intent.Weather:
 // We haven't implemented the GetWeatherDialog so we just display a TODO message.
 var getWeatherMessageText = "TODO: get weather flow here";
 var getWeatherMessage = MessageFactory.Text(getWeatherMessageText, getWeatherMessageText, InputHints.IgnoringInput);
 await turnContext.SendActivityAsync(getWeatherMessage, cancellationToken);
 var attachments = new List<Attachment>();
 meesageReply = MessageFactory.Attachment(attachments); //new variable
 messageReply.Attachments.Add(Cards.CreateAdaptiveCardAttachment());
 break;
